By the summer of 1775, Grant returned to active service with the rank of colonel. He was ordered to return to North America. He arrived in
Boston, Massachusetts, on 30 July. In the aftermath of the
Battle of Bunker Hill, he urged
General Gage to move the British troops to New York City, so that they would have room to manoeuvre. His advice was ignored at the time. Grant was a supernumerary until December when he was made colonel and commander of the
55th Regiment of Foot. He would hold that command until 1791. His prediction that Boston was an untenable position was proved correct the following spring. On 17 March 1776, he accompanied the general withdrawal of British troops to
Halifax,
Nova Scotia. By the summer of 1776,
General William Howe had replaced Gage as commander, and took Grant's advice about securing New York. Grant was given the provisional rank of major-general and played several key parts in Howe's movements. Fortunately for the Americans, Howe refused some advice from Grant, who proposed burning Boston,
Marblehead, Massachusetts; New York City, and Philadelphia.
Battle for New York As the British tried to gain control of the major port city in the
New York Campaign, Grant had become Howe's primary planning officer. He developed two plans, each designed to both gain control of territory and to deal a serious or fatal blow to the
Continental Army. These resulted in the
Battle of Brooklyn, and
Battle of White Plains. Both of these were British victories, as was the overall campaign, but General
Washington avoided the death blow to his troops each time. In the Battle of Long Island on 26 and 27 August, Major General Grant led the division that landed on the left wing. He was to engage the American right and divert attention from Howe's flanking manoeuvre with the main body. An advance unit of his troops engaged the Americans at the
Red Lion Inn, which was the first engagement of the battle. Grant completed his mission, and strongly defeated the American General
William Alexander's division. After the event, Grant was criticised by some for allowing the escape of most of this force. He had almost 7,000 men in ten regiments opposing Alexander's 1,600 Continentals, but there were factors at play other than troop strength. First, Grant stopped his advance according to the British plan, awaiting Howe's attack on the American rear, rather than attacking the Americans who were dug in on the Brooklyn heights. Second, he was running low on ammunition. Boats and logistic support were busy ferrying and supplying the
Hessian units on the right and the main body that was landing at
Gravesend, Brooklyn. Grant quick-marched his battalion to the Battle of White Plains, but he arrived too late. In 1777, Grant devised the battle plans for the
Battle of Brandywine Creek.
Philadelphia and the West Indies Grant was unsuccessful in trapping
Gilbert du Motier, marquis de Lafayette, at the
Battle of Barren Hill, on 20 May 1778. Lafayette held the position along the
Schuylkill River with 2,200 troops and five guns. His front was picketed by 150 light infantry and 50
Oneida Indians under
Allen McLane and his left was held by
James Potter and 600 Pennsylvania militia. The bulk of his command was formed by a veteran brigade under
Enoch Poor.
Sir William Howe sent Grant with 6,000 men and 15 guns to circle wide to the right and come in behind Lafayette's force, while he attacked in front with 4,000 soldiers.
Charles Grey with 2,000 British and Hessian grenadiers was ordered to strike the American left flank. The manoeuvre began auspiciously when Potter's militia dispersed in the face of Grant's column. However, the capture of two of Grey's soldiers warned Lafayette of his danger. Meanwhile, Grant halted his troops to wait for Grey to appear and this allowed the Americans to begin moving back to Matson's Ford. When Grant finally lurched forward again, Lafayette sent some of Poor's troops forward in a feint. Grant was fooled and stopped his advance a second time. By the time he realised what was happening, most of the Americans had slipped out of his grasp via a road that the British were not aware of. Grant nevertheless unleashed his cavalry in pursuit, but they took the wrong route and only arrived in time to see the last of Lafayette's men crossing at Matson's. Finally, Grant was shipped off to the West Indies. On 27 October 1778 he led a successful expeditionary force to capture the French West Indian island of
St. Lucia. A superior French garrison, surrendered on 28 December, at the Battle of La Vigie. On 1 April 1779,
Lord Germain instructed Grant to establish small garrisons throughout the West Indies. Grant had the moral courage to defy Germain and refused to carry out this order. In his letters of 8 and 17 July, he pointed out to the Secretary of State for America that naval superiority was paramount and that the small detachments on every island would not be wise. Instead, he deployed the West Indies garrisons to cover the major naval bases. He posted the
15th,
28th, and
55th Foot and 1,500 gunners at
Saint Kitts. The
27th,
35th, and
49th Foot and 1,600 gunners defended
Saint Lucia. Meanwhile, the royal dockyard at
Antigua was held by an 800-man garrison of the
40th and
60th Foot. Grant also reinforced the fleet with 925 soldiers. He embarked for England on 1 August 1779, but his dispositions provided the basis for the British successes in the Caribbean during the final years of the war. ==Later career==
